Hello. I am porting my program which is initially written in assembly for Linux/Intel to Solaris
I use my own routines to allocate/free memory, using the possibility of anonymously mmap in Linux. For that I declare mmap_ structure .section .data .comm mmap_, 24 Fill it with necessary parameters .section .text movl $0, mmap_ #movl $65535, mmap_+4 # length of requested memory movl $3, mmap_+8 # read, write, PROT_WRITE | PROT_READ, 0x02, 0x01 movl $34, mmap_+12 # map anonymously (0x20), map_private (0x2) movl $-1, mmap_+16 # fd, -1 for portability movl $0, mmap_+20 # offset is ignored And when it is necessary to request memory I do .section .text movl $SIZEOFREQUESTEDMEMORY, mmap_+4 movl $90, %eax # mmap sys call leal mmap_, %ebx int $0x80 And since that pointer to the new memory is in %eax movl %eax, pointer To free memory, I do simply movl $91, %eax # number of syscall movl pointer, %ebx movl $SIZEOFREQUESTEDMEMORY, %ecx int $0x80 This is free() And now I'd like to do the same in OpenSolaris I know, that I must push parameters to the stack, instead of writing in registers. But I do not exactly know where to search for syscall numbers and description, and do I need to do an extra pushl $0 as in FreeBSD for example. If anyone can provide an example of calling mmap/munmap kernel call in assembly that would be nice. I also want to do a 64bit port of my appliation, and again, in Linux everything clear, and if someone mention how to do it in 64bit as well it would be perfect. It is not a student assignment, I have been graduated more than 15 years ago. Thank you P. S. Any link to Solaris assembly programming documentation would be very useful. -- This message posted from opensolaris.org _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
